Abstract
Provided is a method for matching a virtual scene of a remote scene with a real scene for augmented reality and mixed reality. Multiple coordinate systems are established and a position relationship between the multiple coordinate systems is determined. A position of a point cloud scene in the near-side environmental space and the position of the near-side virtual scene are determined in the near-side environmental space through real marks, so as to realize the high-precision matching and positioning for augmented reality and mixed reality. Based on the position of objects marked in the real space, the method realizes adaptive and accurate positioning of the virtual objects in the augmented reality and mixed reality by overcoming spatial barriers. The scene in the virtual space is accurately superimposed into the near-side environmental space.
